I've been searching
around to see if there is a patch to repair the problem I have with my DVDROM
drive on my Tibook and I found your correspondance. The drive is a Matsushita
SR-8717 with driver version 1.4.7 and revision number HA18. It stopped working
when I was copying one of my CD's into iTunes. The disk just stopped loading and
the program hung up. I rebooted and after that it just spat out audio CD's after
appearing to fail to find the start point on the disk. Same with Data CD. DVD
still plays with no problems.

This may not be your
area but any advice you have would be greatly appreciated.

Is the problem
likely to be in the drive or in the computer?

Can I fix it by
downloading software/firmware?

Should I just
replace the drive ( I'm out of warranty)?

Is there a
diagnostics application I can use to investigate the problem further? (I can't
load my Apple hardware troubleshooter disk as the drive won't read
it)
